Hey all, im having a bit of problems understanding what this particular homework problem means. I have an idea but anyways here is the question:
"Show the logic diagram in order to perform A + 2's Complement of B."
It is in the portion of the book with shift registers so I must use that in my design.
Anyways, what I am having trouble understanding is A+2's complement of B. I just dont understand what it is asking. Is do I take the complement of A and then add 2 (0010)? or Do I take the compliment of B or what or do I add 2 to A then take the compliment. Any ideas?
All feedback is appreciated, thanks.
